[Theory-seminars] Theory Seminar Wednesday - Bijaya Acharya

[Colin Egerer]

Hello All,

This coming Wednesday, March 22nd, at 1:00 PM (EDT), Bijaya Acharya will give our next hybrid theory seminar. We want to highlight that this seminar is one of the ODU + JLab joint position interviews. If you will be on-site and are comfortable doing so, please join us in room L102 of CEBAF Center. Otherwise, Bijaya's seminar will also be provided virtually on our usual ZoomGov link: https://jlab-org.zoomgov.com/j/1611179843?pwd=M09CNTFpbFVZSW1IQlhIMGp3RUVHUT09

Please see below for the title and abstract.

Theory Seminar
Wednesday, March 22nd at 1:00 PM

Bijaya Acharya (Oak Ridge National Laboratory)
will discuss "Nuclear electroweak structure in chiral effective field theory"

Abstract:
Chiral effective field theory provides nuclear interactions and electroweak currents as controlled approximations to quantum chromodynamics and electroweak theory at momenta relevant for nuclear processes. In this talk, I will outline our recent progress that has enabled computation of lepton-nucleus quasielastic scattering observables in the ab initio coupled-cluster method. I will present predictions for several nuclear electroweak observables: proton-proton fusion, quasielastic electron scattering on deuteron, He-4, O-16, and Ca-40, magnetic moments in the Ca isotopic chain, and magnetic transition in Ca-48. I will highlight the astrophysical and experimental implications of these results, and discuss some of the remaining challenges.

Best Regards,
Caroline, Colin, & Patrick
